We sell tons of ebikes with Enviolo for years, they are fantastic on ebikes and I highly recommend it especially with a belt it is a pretty much literally a no-maintenance drivetrain minus some cable replacements every once and while or more if you are rough with the shifter. I must also say the little orange figure is really fun (I know the new systems it is grey) but it adds some fun. I am personally not a fan of the Automatiq system as you cannot manually shift but the concept is pretty cool and can help open cycling up to a lot more people who don't want to shift or have issues with their hands or something so shifting is tough,
